HOUSTON (NASA PR) — Getting sick is no fun for anyone, but it especially taxes crew members aboard the ISS. Protecting crew health is important as NASA prepares for long-duration, deep-space missions. The human immune system is a complex web of biological structures and processes; decreased activity in one piece of it can change overall disease risk. Studies have shown microgravity causes modifications in the human immune system. Figuring out why and how this occurs could help not only astronauts, but people affected by immune dysfunction here on Earth.
NASA has replaced an astronaut set to launch to the International Space Station (ISS) in June with a backup.
Jeanette Epps, who was set to become the first African American crew member on the space station, has been reassigned to the Astronaut Office at NASA’s Johnson Space Center, the space agency announced. She will be considered for future flights.
“Serena Auñón-Chancellor, who previously was assigned to Expedition 58/59, has been reassigned to the Expedition 56/57 crew, launching in June,” NASA said in a press release. ” Anne McClain, a member of the 2013 astronaut class, will fly on the Expedition 58/59 crew, launching in November.”
NASA did not give provide a reason for the reassignment of Epps, who was selected as an astronaut in 2009.
